Abstract

Aircraft and balloon in situ measurements of CH 4 and HCl using cw distributed feedback (DFB) interband cascade (IC) lasers arereported. In the stratosphere and upper troposphere, sensitivity toward CH 4 and HCl is better than 10   ppbv (1 s) and 90   pptv (50 s), respectively. These are the first flight measurements of trace gas-phase species using cw DFB IC lasers.
